what if there was a ramp for each robot, different slopes worth different points and changing slopes scoring bonus points, and with 30 secs or so remaining, the field was floded with 4-6 inches of water. the winner being the bot highest on its ramp. adding a challenge, make a way for the robot to attach itself to a cable and winch itself up the ramp...but we would need to have power to undo the cables...
